FIG. 3 is a diagram 300 illustrating a non-limiting example of variouscommunications at various times according to some aspects of the presentdisclosure. FIG. 3 is a diagram 300 illustrating non-limiting examplesof various communications between AP 110 and STA 120 according tovarious aspects of the present disclosure. In some aspects, at one ormore times (e.g., including T₁ and/or T₂), AP 110 may communicate withSTA 120. In some aspects, such communications may pertain tocapabilities, parameters, settings, configurations, and other aspectsthat may affect one or more states, modes, configurations, parametersand/or future communications between AP 110 and STA 120.

In some aspects, AP 110 and STA 120 may negotiate various parameters,settings, and/or configurations, which may relate to operation(s) of AP110, STA 120, PR 222 and/or SR 224. In some aspects, at time T₁, STA 120may transmit and AP 110 may receive an UL communication 310. In someaspects, the UL communication 310 may be or include a request, a requestpacket, a timing management signal, a timing signal, and other suitableterms without deviating from the scope of the present disclosure.Various aspects related to such UL communication 310 are provided ingreater detail throughout the present disclosure.

Inother words, any description provided herein with reference to an ‘ULcommunication 310’ may be included in a singular UL transmission orincluded in different UL communications occurring at different times,and/or any description provided herein with reference to ‘DLcommunication 312’ may be included in a singular DL transmission orincluded in different DL communications occurring at different times.

In some aspects, STA 120 may utilize PR 222 for UL communication 310and/or DL communication 312, but STA 120 may alternatively utilize itsSR 224 for UL communication 310 and/or DL communication 312 withoutdeviating from the scope of the present disclosure. Although theillustration provided in FIG. 3 depicts that, in some aspects, such ULcommunication 310 may occur prior to such DL communication 312, this maynot necessarily be a limitation of the present disclosure. For example,in some aspects, such DL communication 312 may occur prior to such ULcommunication 310 without deviating from the scope of the presentdisclosure. Although the illustration in FIG. 3 depicts that, in someaspects, both UL communication 310 and such DL communication 312 canoccur, this may not necessarily be a limitation of the presentdisclosure. For example, in some aspects, such UL communication 310 mayoccur without such DL communication 312 ever occurring, and, in someother aspects, such DL communication 312 may occur without such ULcommunication 310 ever occurring.

In some aspects, certain communications (e.g., DL communication 310and/or UL communication 312) may occur while PR 222 222 is in a highpower state/mode 314. In some aspects, certain communications (e.g., DLcommunication 310 and/or UL communication 312) may occur while the SR224 is in a low power state/mode 316. Generally, the term ‘high powerstate/mode’ may alternatively or interchangeably be referred to as anactive state/mode, awake state/mode, an on state/mode, a powered up/onstate/mode, a turned up/on state/mode, and/or various other suitableterms without deviating from the scope of the present disclosure. Insome aspects, the term ‘high power state/mode’ may refer to a state/modein which the power utilized (e.g., by PR 222 and/or SR 224) is above orgreater than a certain threshold value (e.g., threshold power value).Generally, the term ‘low power state/mode’ may alternatively orinterchangeably be referred to as a doze state/mode, a power-savestate/mode, an off state/mode, a powered down/off state/mode, a turneddown/off state/mode, and/or various other suitable terms withoutdeviating from the scope of the present disclosure. In some aspects, theterm ‘low power state/mode’ may be referred to as a state/mode in whichno/zero power is utilized (e.g., by PR 222 and/or SR 224). In someaspects, the term ‘low power state/mode’ may refer to a state/mode inwhich the power utilized (e.g., by PR 222 and/or SR 224) is below orless than a certain threshold value (e.g., threshold power value).

In some aspects, the PR 222 may sometimes alternate between a high powerstate/mode 314, 334 and a low power state/mode 322. Such alternating mayoccur when STA 120 or its PR 222 is in a power-save state/mode or a dutycycle state/mode. Although such alternating is illustrated in FIG. 3, insome aspects, the PR 222 may not perform such alternating and may be ina, e.g., continuous high power state/mode (e.g., without the low powerstate/mode 322). In some aspects, the SR 224 may sometimes alternatebetween a high power state/mode 324, 328 and a low power state/mode 316,326, 336. Such alternating may occur when STA 120 or its SR 224 is in apower-save state/mode or a duty cycle state/mode. Although suchalternating is illustrated in FIG. 3, in some aspects, the SR 224 maynot perform such alternating and may be in a, e.g., continuous highpower state/mode (e.g., without the low power state/mode 326). Variousaspects pertaining to certain states, modes, configurations, andparameters associated with operation(s) of STA 120, the PR 222, and/orthe SR 224 is provided throughout the present disclosure.

In some aspects, STA 120 may await receipt, e.g., at/including times T₃,T₄ and T₅, which may be while the PR 222 is in the low power state/mode322. In some aspects, at time T₆, AP 110 may transmit and STA 120 mayreceive a packet 320. In some aspects, the SR 224 receives the packet320 while the SR 224 is in a high power state/mode 328. In some aspects,the PR 222 may be in a while low power state/mode 322 when AP 110transmits and STA 120 (e.g., utilizing SR 224) may receive the packet320. In some aspects, the packet 320 may alternatively orinterchangeably be referred to as an awaken packet, an awake packet, anawaken request packet, and/or various other suitable terms withoutdeviating from the scope of the present disclosure. Various aspectsrelated to the packet 320 and operations by STA 120 in relation to thepacket 320 are provided throughout the present disclosure.

In some aspects, following communication of the packet 320, STA 120 mayinitiate, e.g., at time T₇, a transition of the PR 222 from a low powerstate/mode 322 to a high power state/mode 334. For example, after atransition period 338, the PR 222 may be in a high power state/mode 334by time T₈. In some aspects, the SR 224 may be in a low power state/mode336 after the PR 222 transitions to a high power state/mode 334.

In some aspects, at time T₉, STA 120 (e.g., utilizing PR 222) maytransmit and AP 110 may receive a message 330.

In some aspects, AP 110 may transmit and STA 120 may(e.g., using PR 222) receive a timing management signal configured toset or affect a beginning time corresponding to receiving of the packet320 (e.g., awaken request packet). In some aspects, AP 110 may transmitand STA 120 may (e.g., using PR 222) receive a timing management signaland, based on the received timing management signal, set or affecttiming aspects, including a beginning time, a duration, and/or an endtime, of operating SR 224 in a high power state/mode or ofpowering/turning up/on SR 224 (e.g., in a high power state/mode). Insome aspects, AP 110 may transmit and STA 120 may (e.g., using PR 222)receive a timing management signal configured to set or affect timinginformation, including a duration of time to operate SR 224 in a highpower state/mode or to maintain or power on/up SR 224 (e.g., in a highpower state/mode), corresponding to communication of the packet 320(e.g., awaken packet) and/or its response 330 (e.g., response to awakenpacket).

In some aspects, the apparatus may receive a timing management signal.The timing management signal may include, be utilized for, and/or beconfigured to set, modify, adjust, confirm, and/or otherwise affecttiming information (e.g., a start/starting time, a beginning time, anend/ending time, a duration, a time period, a timing offset, timinginformation or a start time of a subsequent timing management signal, aduration of time to maintain or power/turn on/up a primary/main and/orsecondary radio(s)/receiver(s), etc.) corresponding to communication(e.g., reception/transmission) of the (e.g., current or one or moresubsequent) awaken packet(s) and/or response packet(s) by the apparatus.In some aspects, the apparatus may set, modify, adjust, confirm, and/orotherwise affect a timing aspect e.g., a start/starting time, abeginning time, an end/ending time, a duration, a time period, a timingoffset, timing information or a start time of a subsequent timingmanagement signal, a duration of time to maintain or power/turn on/up aprimary/main and/or secondary radio(s)/receiver(s), etc.) ofpowering/turning/keeping-powered on/up of the primary/mainradio(s)/receiver(s) and/or secondary radio(s)/receiver(s) based on thetiming management signal.

In some aspects, the timing management signal may comprise a sequencemodulated by any of the keying/modulation techniques, such as frequencyshift keying, amplitude shift keying, phase shift keying, on off keying,quadrature amplitude modulation, and/or various other types ofmodulation or keying/modulation techniques. In some aspects, the timingmanagement signal may be detected by the secondary radio(s)/receiver(s)without utilizing the primary/main radio(s)/receiver(s) (e.g., while theprimary/main radio(s)/receiver(s) is powered/turned off/down). In someaspects, the timing management signal may be communicated (e.g.,received) periodically.

In some aspects, the apparatus may detect/determine that the timingmanagement signal was not received (e.g., during an expectedtime/time-period, based on its periodicity). In response, the apparatusmay modify, update, revise, and/or alter a timing aspect (e.g., astart/starting time, a beginning time, an end/ending time, a duration, atime period, a timing offset, etc.) of its primary/mainreceiver(s)/radio(s) and/or secondary receiver(s)/radio(s). In someaspects, this may be performed in a manner that increases a likelihoodthat a subsequent timing management signal will be received/detected bythe apparatus and/or its primary/secondary radio(s)/receiver(s). In someaspect, the likelihood may be increased by increasing the power on/upduration/period of the primary/main radio(s)/receiver(s) and/orsecondary radio(s)/receiver(s) (relative to a preceding power on/upduration/period of the primary/main radio(s)/receiver(s) and/orsecondary radio(s)/receiver(s)).

In some aspects, the DL communication 312 includes a packet (e.g.,request packet) that includes a parameter corresponding to a mode/stateassociated with STA 120. In some aspects, AP 120 transmits and STA 120receives (e.g., using PR 222) the packet (e.g., request packet) thatincludes the parameter corresponding to a mode associated with STA 120,and STA 120 waits, based on the received parameter, to operate PR 222 ina high power state/mode or to turn on/up PR 222 until a time thatcorresponds to that mode/state.

As described herein, a packet (e.g., awaken request packet) maysometimes be referred to as a frame (e.g., awaken frame), beacon (e.g.,awaken beacon), signal (e.g., awaken signal), transmission (e.g., awakentransmission), communication (e.g., awaken communication), and/orvarious other suitable terms without necessarily deviating from thescope of the present disclosure.

After, in response to, and/or in associationwith receiving such and/or based on suchfield/parameter/indication/data/information, an apparatus (e.g., STA(s)may wait to turn-on/activate/enable/duty-cycle-on/power-up/power-on itsprimary/main radio/receiver and/or secondary radio/receiver until atime/duration/period that corresponds to the indication, purpose,intention, objective, or other state/mode/configuration. For example, ifsuch indication, purpose, intention, objective, and/or otherstate/mode/configuration indicates a time/duration/period that asubsequent/next/later DL communication of interest will be transmittedfrom one apparatus (e.g., AP) to another apparatus (e.g., that/thoseSTA(s)), then the apparatus (e.g., STA(s)) may determine to notturn-on/activate/enable/duty-cycle-on/power-up/power-on its primary/mainand/or its secondary radio/receiver until a time/period/duration thatcorresponds to that DL communication of interest, which can conservepower that might otherwise be expended during a correspondingduration/period of time.

Such subsequent/next/later DL communication may or may not be the DLcommunication that immediately follows DL communication of theaforementioned packet (e.g., awaken request packet) and/or beacon (e.g.,awaken beacon). For instance, one or more DL communications (e.g., notof interest to that/those STA(s)) may occur in between thatpacket/beacon and the DL communication of interest. Non-limitingexamples of such DL communication(s) of interest may include but may notbe limited to another packet, another beacon, another signal, anothertransmission, which may or may not includeinformation/parameter/field/indication corresponding to trafficinformation (e.g., traffic information message), delivery information(e.g., delivery traffic information message), a group identifier/addressinformation (e.g., associated identifier message), receiver/receptioninformation (e.g., receiver/reception indication), on-durationinformation (e.g., a duration/period of time to maintain one or more ofits radio(s)/receiver(s) in an on/powered-on/powered-up), and/or variousother suitable types of information.

In someaspects, awakening PR 222 may refer to switching from operating PR 222in a low/lower power state/mode to operating PR 222 in a high/higherpower state/mode. As described in greater detail herein, in someaspects, a low/lower power state/mode may refer to operating a radio(e.g., PR 222 and/or SR 224) according to a power state/mode that isless than a threshold power value, and/or a high/higher power state/modemay refer to operating a radio (e.g., PR 222 and/or SR 224) according toa power state/mode that is greater than a threshold power value.

In some aspects, an apparatus (e.g., AP/STA) may receive/transmitinformation that incorporate, integrate, encode, combine, merge, embed,or otherwise include information associated with a basic service set(e.g., to which that apparatus (e.g., AP) or another apparatus (e.g.,that receiving STA, another STA, etc.) is associated) in/within/into anumber, value, field, parameter, or other data portion (e.g., a dataportion that is included in an end portion of acommunication/transmission (e.g., instead of having an explicit dataportion that includes only such information associated with the basicservice set)). In some aspects, such number, value, field, parameter, orother data portion includes information that serves more than onefunction, wherein one of the more than one function is to provideinformation associated with the basic service set. Such number, value,field, parameter, or other data portion may be, for example, anerror-detecting code/value/number, a cyclic redundancy checkvalue/number/sequence/code, a frame check sequence/value/number/code. Insome aspects, an apparatus may, based on such number, value, field,parameter, or other data portion, determine two or more information,wherein at least one of such information includes information associatedwith the basic service set (e.g., the apparatus may determine whetherthe data packet, field, information, etc. that included such number,value, field, parameter, or other data portion was destined to thatapparatus (e.g., the apparatus that received it) based on suchinformation associated with the basic service set) (e.g., the apparatusmay determine whether the data packet, field, information, etc. thatincluded such number, value, field, parameter, or other data portion isassociated with the basic service set to which the that apparatus (e.g.,the apparatus that received it) is associated) (e.g., the apparatus mayobtain or associate its basic service set information from the basicservice set information included in the data packet, field, information,etc. that included such number, value, field, parameter, or other dataportion was destined to that apparatus (e.g., the apparatus thatreceived it)).

In some aspects, the UL communication 310 may be or include a fieldindicating a duration of time during which SR 224 will operate accordingto a high/higher power state/mode or on-mode during/for the one or moresubsequent/future communications. Accordingly, in some aspects, STA 120may transmit (e.g., using PR 222) and AP 110 may receive the fieldindicating a duration of time during which SR 224 will operate accordingto a high/higher power state/mode or on-mode during the one or moresubsequent/future communications.

Forexample, the null portion may have a duration that is one fourth (e.g.,A/4 microseconds) of the on/on-duration signal(s)/symbol(s) (Amicroseconds), and the payload/signal portion may have a duration thatis three quarters (e.g., 3A/4 microseconds) of the on/on-durationsignal(s)/symbol(s) (e.g., A microseconds).

In some aspects, the first data rate may be less than the second datarate, or the second data rate may be greater than the first data rate.In some aspects, the second data rate may be lower than the first datarate, or the first data rate may be greater than the second date rate.Although various data rates (e.g., first and second data rates) aredescribed herein, in some aspects, a single data rate (e.g., only afirst data rate or only a second data rate) may be sufficient andadditional data rates are not necessarily a requirement of the presentdisclosure, while, in some other aspects, more than a single data rate(e.g., a first data rate and a second data rate) may be required and asingle data rate may not necessarily be sufficient. Therefore, variousimplementations may utilize a single data rate or more than a singledata rate without deviating from the scope of the present disclosure.

In some aspects, a communication/transmission (e.g., packet 320)transmitted by AP 110 and received by STA 120 may not include a fieldthat explicitly indicates a data rate of the transmission/communication(e.g., packet 320). In some aspects, the SS includes information usefulfor an inference (e.g., by STA 120) of a rate of transmission ofinformation in the communication/transmission (e.g. packet 320). In someaspects, STA 120 may infer a first magnitude of the one or more factorswhen the SS includes the first set/structure of data, and infer a secondmagnitude of the one or more factors when the SS includes the secondset/structure of data. In such aspects, the first set/structure of datais different from the second set/structure of data. In such aspects, thefirst magnitude of the one or more factors is higher than the secondmagnitude of the one or more factors, or the second magnitude of the oneor more factors is less than the first magnitude of the one or morefactors. In such aspects, the first set/structure of data of the SS hasa relationship to the second set/structure of data of the SS, or thesecond set/structure of data of the SS has a relationship to the firstset/structure of data of the SS. The second set/structure of data of theSS may be or include a complement of the first set/structure of data ofthe SS.

In some aspects, a quantity of bits of the first set/structure of dataof the SS is a fraction of a quantity of bits of the secondset/structure of data of the SS. In some aspects, the number ofbits/symbols and/or the duration of the first set/structure of data ofthe SS is greater than the number of bits/symbols and/or the duration ofthe second set/structure of data of the SS, or the number ofbits/symbols and/or the duration of the second set/structure of data ofthe SS is less than the number of bits/symbols and/or the duration ofthe first set/structure of data of the SS. In some other aspects, thenumber of bits/symbols and/or the duration of the second set/structureof data of the SS is greater than the number of bits/symbols and/or theduration of the first set/structure of data of the SS, or the number ofbits/symbols and/or the duration of the first set/structure of data ofthe SS is less than the number of bits/symbols and/or the duration ofthe second set/structure of data of the SS.

As mentioned herein, in some aspects, the second data rate may be lowerthan the first data rate, or the first data rate may be greater than thesecond date rate. In some aspects, e.g., when communication of thepacket 320 is according to a particular data rate (e.g., a low datarate, or a single, predetermined data rate), an on (or on-duration)signal may be characterized by having an energy level above a threshold(e.g., threshold energy level), and an off (or off-duration) signal maybe characterized by having an energy level below the threshold (e.g.,threshold energy level). In such aspects, if, during the period of time,STA 120 receives a group that includes at least three signals where aninitial signal is the same as the penultimate signal and the finalsignal of the group comprises an off signal, STA 120 may determine thatthe group of signals received during the period of time corresponds to afirst value. In such aspects, if, during the period of time, STA 120receives a group that includes at least three signals where an initialsignal is the same as the penultimate signal and the final signalincludes an on signal, STA 120 may determine that the group of signalsreceived during the period of time corresponds to a second value, whichmay be different from the first value.

In some aspects, as described above, a received packet (e.g., an awakenpacket, an awaken request packet, etc.) may be modulated in various wayswithout deviating from the scope of the present disclosure. In someaspects, as described above, the packet (e.g., an awaken packet, anawaken request packet, etc.) may be modulated using variouskeying/modulation techniques, such as frequency shift keying, amplitudeshift keying, phase shift keying, on off keying, quadrature amplitudemodulation, and/or various other types of modulation orkeying/modulation techniques. In some aspects, the on off keying may beconfigured in various ways without deviating from the scope of thepresent disclosure. In some aspects, the on off keying may be configureddifferently based on the rate of data transmission of the packet (e.g.,an awaken packet, an awaken request packet, etc.).

In some aspects, when communication of the packet (e.g., an awakenpacket, an awaken request packet, etc.) is according to a second datarate, which may be the same as or different from (e.g., lesser/lowerthan or greater/higher than) the aforementioned first data rate(described above), an apparatus (e.g., STA/AP) may determineinformation, a value, or an information/informational value associatedwith symbols/signals received during a certain period of time. In someaspects, such an apparatus (e.g., STA/AP), when communicating accordingto such second data rate, may determine that the symbols/signalsreceived during such a period of time contains or corresponds to a firstvalue/information/informational-value when/if, during such a period oftime: (1) such apparatus receives/received a group of at least threesignals/symbols comprising no more than two or two or moreon/on-duration signal(s)/symbol(s) (e.g., wherein an on/on-durationsignal/symbol may be characterized by having a detectable energy levelabove a certain threshold) separated by no more than one or more thanone off/off-duration signal(s)/symbol(s) (e.g., wherein anoff/off-duration signal/symbol may be characterized by having adetectable energy level below a certain threshold), and wherein afinal/last symbol/signal of such grouping is/includes/comprises anoff/off-duration signal/symbol; (2) such apparatus receives/received agroup of at least three signals/symbols comprising no more than two ortwo or more off/off-duration signal(s)/symbol(s) separated by no morethan one or more than one on/on-duration signal(s)/symbol(s) and whereina first/initial symbol/signal of such grouping is/includes/comprises anon/on-duration signal/symbol; and/or (3) such apparatusreceives/received a group of at least three signals/symbols wherein aninitial symbol/signal is similar or the same as the penultimatesignal/symbol (e.g., both on/on-durations signals/symbols or bothoff/off-duration symbols/signals) and (i) the last/final symbol is anoff/off-duration symbol/signal and/or (ii) the first/initialsymbol/signal is an on/on-duration signal/symbol. In some aspects, theduration of time associated with each signal/symbol described above isthe same (e.g., each comprises A microseconds). In some aspects, aduration of time associated with each signal/symbol described above isdifferent from one another (e.g., one signal/symbol may have a durationof A microseconds while one (or more) signal(s)/symbol(s) may have aduration of B microseconds).

In some aspects, such an apparatus (e.g., STA/AP), when communicatingaccording to such second data rate, may determine that thesymbols/signals received during such a period of time contains orcorresponds to a second value/information/informational-value, which maybe the same as or different from the aforementioned firstvalue/information/informational-value (described above), when/if, duringsuch a period of time: (1) such apparatus receives/received a group ofat least three signals/symbols comprising no more than two or two ormore on/on-duration signal(s)/symbol(s) (e.g., wherein an on/on-durationsignal/symbol may be characterized by having a detectable energy levelabove a certain threshold) separated by no more than one or more thanone off/off-duration signal(s)/symbol(s) (e.g., wherein anoff/off-duration signal/symbol may be characterized by having adetectable energy level below a certain threshold), and wherein afinal/last symbol/signal of such grouping is/includes/comprises anon/on-duration signal/symbol; (2) such apparatus receives/received agroup of at least three signals/symbols comprising no more than two ortwo or more off/off-duration signal(s)/symbol(s) separated by no morethan one or more than one on/on-duration signal(s)/symbol(s) and whereina first/initial symbol/signal of such grouping is/includes/comprises anoff/off-duration signal/symbol; and/or (3) such apparatusreceives/received a group of at least three signals/symbols wherein aninitial symbol/signal is similar or the same as the penultimatesignal/symbol (e.g., both on/on-durations signals/symbols or bothoff/off-duration symbols/signals) and (i) the last/final symbol is anon/on-duration symbol/signal and/or (ii) the first/initial symbol/signalis an off/off-duration signal/symbol. In some aspects, a duration oftime associated with each signal/symbol described above is differentfrom one another (e.g., one signal/symbol may have a duration of Amicroseconds while one (or more) signal(s)/symbol(s) may have a durationof B microseconds). In some aspects, a duration of time associated witheach signal/symbol described above is similar to or the same as oneanother (e.g., one signal/symbol may have a duration of A microsecondswhile one (or more) signal(s)/symbol(s) may have a duration of exactlyor approximately A microseconds).

In some aspects, the packet 320 may include a preamble. In some aspects,the preamble is communicated using a first bandwidth or a firstfrequency range, and the SS is communicated using a second bandwidth orsecond frequency range. In some aspects, the first bandwidth or firstfrequency range comprises a value or range of values that is greaterthan or a multiple of the second bandwidth or second frequency range. Insome aspects, such multiple comprises a value of X, which may be aninteger greater than one. In some aspects, the first bandwidth orfrequency range comprises a same center frequency as the secondbandwidth or second frequency range.

In some aspects, such field(s),signal(s), bit(s), or portion(s) may include or be a preamble, a header,a timing management signal, a synchronization value/counter/signal,and/or various other suitable types of information/data, as described ingreater detail herein. In some aspects, the preamble and/or header ofsuch field(s), signal(s), bit(s), or portion(s) may be communicatedusing/in, be included in, or span a first bandwidth or first frequencyrange, and the timing management signal, synchronizationvalue/counter/signal, and/or one or more other portions of suchfield(s), signal(s), bit(s), or portion(s) may be communicated using/in,be included in, or span a second bandwidth or second frequency range. Insome aspects, the first bandwidth or first frequency range comprises avalue or a range of values that is greater than, or a multiple of (e.g.,2X/2-times, 3X/3-times, 4X/4-times, 5X/5-times, 6X/6-times etc.), thesecond bandwidth or second frequency range. In some aspects, the firstbandwidth or first frequency range comprises a same center frequency asthe second bandwidth or second frequency range.

In some aspects, the second bandwidth or second frequency rangecomprises a value or a range of values that is less than, a subset of,or a fraction of (e.g., one-half, one-third, one-fourth, one-fifth,one-sixth, etc.) the second bandwidth or second frequency range. In someaspects, no more than a single timing management signal and/orsynchronization signal (of such field(s), signal(s), bit(s), orportion(s)) spanning, communicated in/using, or included in the secondfrequency range or second bandwidth is communicated with the headerand/or preamble (of such field(s), signal(s), bit(s), or portion(s))spanning, communicated in/using, or included in the first frequencyrange or first bandwidth. In some aspects, at least a portion or some ofthe first bandwidth or first frequency range is included in the secondbandwidth or second frequency range, and at least a portion or some ofthe first bandwidth or first frequency range is not included in thesecond bandwidth or second frequency range. In some aspects, all of thesecond bandwidth or second frequency range is included in or is the sameas the first bandwidth or first frequency range, and not all of thefirst bandwidth or first frequency range is included in or the same asthe second bandwidth or second frequency range.

In some aspects, in response to receiving the packet 320, STA 120 mayinitiate a transition of PR 120 from a low power state/mode, turned offstate or powered down state to a high power, turned on state, or poweredup state. In some aspects, STA 120 may transmit and AP 110 may receive aresponse 330 to the packet 320. STA 120 may transmit the response 330utilizing PR 222, as illustrated in FIG. 3, or SR 224, even though notillustrated in FIG. 3. In some aspects, after transmitting the response330 to the packet 320, AP 110 may transmit and STA 120 may receive amessage 332, which may be communicated in association with theaforementioned response 330. STA 120 may receive the message 332utilizing PR 222, as illustrated in FIG. 3, or SR 224, even though notillustrated in FIG. 3. In some aspects, in response to receiving themessage 332, AP 110 may initiate a transition from operating accordingto a mode/state wherein SR 224 is in a high power state/mode, turned on,or powered up to operating according to a mode/state wherein SR 224 isin a low power state/mode, turned off, or powered down. In some aspects,if/after STA 120 transmits the response 330 (e.g., using PR 222 and/orSR 224) to the packet 320 to AP 110 and if/after STA 120 receives apacket (e.g., message 332) associated with the transmitted response 330,STA 120 may initiate a transition of SR 224 from a high powerstate/mode, a turned on state, or a powered up state to a low powerstate/mode, a turned off state, or a powered down state.

In some aspects, after AP 110 transmits the packet 320, AP 110 maydetermine whether the transmission was successful based on whether AP110 receives a response 330 to the transmitted packet 320 during apredetermined period of time after the transmission (e.g., during a timeperiod between time T₆ and time T₉). In some aspects, AP 110 maydetermine that the transmission was unsuccessful if no response to thepacket 320 is received (e.g., by time T₉), and/or may determine that thetransmission was successful if a response to the packet 320 was received(e.g., by time T₉).

In some aspects, an apparatus/transmitter (e.g., AP) that transmits anawaken request packet may determine whether such transmission wassuccessful based on whether it receives any (e.g., at least one) packets(e.g., awaken response packets) after, in response to, and/or inassociation with the transmitted awaken request packet during aperiod/duration (e.g., preset, predetermined, variable) of time aftertransmitting the awaken request packet. In some aspects, if theapparatus/transmitter (e.g., AP) receives any (e.g., at least one)packets (e.g., awaken response packet(s)) after, in response to, and/orin association with transmission of the awaken request packet, then theapparatus/transmitter (e.g., AP) may determine that the transmission ofthe awaken request packet was successful. In some aspects, if theapparatus/transmitter (e.g., AP) receives no packets (e.g., awakenresponse packets) After, in response to, and/or in association withtransmission of the awaken request packet, then theapparatus/transmitter (e.g., AP) may determine that the transmission ofthe awaken request packet was unsuccessful.

In some aspects, the received packet 320 includesa field that indicates a version value. In some aspects, STA 120 may doone or more of the following: (A) use the version value to determinewhether settings or parameters associated with a basic service set (BSS)are up-to-date or current; (B) use the version value to determinewhether to update settings or parameters associated with the BSS; and/or(C) compare the version value (included in the received packet 320) witha previously received version value and, based on the comparison, todetermine whether to perform an operation to update the settings orparameters associated with the BSS.

In some aspects, the settings or parameters associated with the BSS mayaffect communications using at least one of PR 222 or SR 224. In someaspects, in response to receiving the version value, and/or based on anyone or more of the aforementioned (A), (B), and/or (C), STA 120 maydetermine to perform an operation to update such parameters or settingsassociated with the BSS. In some aspects, the operation to update thesettings or parameters of the BSS includes STA 120 awakening PR 222. Insome aspect, the operation to update the settings or parameters of theBSS includes STA 120 communicating a request to AP 110 and subsequentlyreceiving a response from AP 110.

In some aspects, an apparatus (e.g. AP) may transmit and anotherapparatus (e.g., STA) may receive a packet, frame, beacon, or otherinformation comprising various field. In some aspects, non-limitingexamples of such packet, frame, beacon, or other information may includean awaken packet, an awaken request packet, an awaken beacon, or variousother suitable forms of data/information. In some aspects, such receivedpacket, frame, beacon, or other information may be received by theprimary/main radio/receiver of the other apparatus (e.g., STA) (e.g.,while the secondary/awaken radio/receiver of the other apparatus (e.g.,STA) is turned off or in a low power state). In some aspects, suchreceived packet, frame, beacon, or other information may be received bythe secondary/awaken radio/receiver of the other apparatus (e.g., STA)(e.g., while the main/primary radio/receiver of the other apparatus(STA) is turned off or in low power state). In some aspects, suchreceived packet, frame, beacon, or other information may include afield, value, counter, indicator, or number of bits that indicates aversion/modification/alteration/synchronization/counter/changenumber/indicia/value. In some aspects, the other apparatus (e.g., STA)may utilize suchversion/modification/alteration/synchronization/counter/changenumber/indicia/value to determine whetherinformation/settings/parameters associated with the basic service set(e.g., with which the apparatus(es) (e.g., AP and/or STA) is/areassociated) (e.g., as stored in/by the other apparatus (e.g., STA)) areupdated/up-to-date/current and/or whether to update suchinformation/settings/parameters associated with the basic service set(e.g., with which the apparatus(es) (e.g., AP and/or STA) is/areassociated) (e.g., as stored in/by the other apparatus (e.g., STA)).

In some aspects, suchinformation/settings/parameters associated with the basic service setmay impact/affect communications by/using the primary/mainreceiver/radio of the apparatus (e.g., STA)). In some aspects, suchinformation/settings/parameters associated with the basic service setmay impact/affect communications by/using the secondary/awakenreceiver/radio of the apparatus (e.g., STA).

After, in response to, and/or in association with receiving theaforementioned information(version/modification/alteration/synchronization/counter/changenumber/indicia/value),or in association with or based upon the aforementioned comparison(comparison of such receivedversion/modification/alteration/synchronization/counter/changenumber/indicia/valuewith a stored or another previously receivedversion/modification/alteration/synchronization/counter/changenumber/indicia/value) (e.g., as stored in/by the other apparatus (e.g.,STA)) or any of the aforementioned determinations (e.g., (i) determiningwhether information/settings/parameters associated with the basicservice set (e.g., with which the apparatus(es) (e.g., AP and/or STA)is/are associated) (e.g., as stored in/by the other apparatus (e.g.,STA)) are updated/up-to-date/current), (ii) determining whether toupdate such information/settings/parameters associated with the basicservice set (e.g., with which the apparatus(es) (e.g., AP and/or STA)is/are associated) (e.g., as stored in/by the other apparatus (e.g.,STA)), (iii) or determine whether to perform an operation to update suchinformation/settings/parameters associated with the basic service set(e.g., with which the apparatus(es) (e.g., AP and/or STA) is/areassociated), the apparatus (e.g., STA) may make a determination.

In some aspects, such a determination is that no further action isrequired in relation to the information/settings/parameters associatedwith the basic service set (e.g., when theinformation/settings/parameters associated with the basic service set isup-to-date). In some actions, such a determination is to perform anoperation to update such information/settings/parameters associated withthe basic service set (e.g., when the information/settings/parametersassociated with the basic service set is not up-to-date). In someaspects, such an operation to update suchinformation/settings/parameters associated with the basic service setmay be for the apparatus (e.g., STA) to awaken or enter into a high(er)power state (e.g., with respect to its primary/main radio). In someaspects, such an operation to update suchinformation/settings/parameters associated with the basic service setmay be for the apparatus (e.g., STA) to update/change its storedversion/modification/alteration/synchronization/counter/changenumber/indicia/value based on the receivedversion/modification/alteration/synchronization/counter/changenumber/indicia/value.
